#5779: _fast_floats_'s pow returns garbage for non-integral powers left of zero
----------------------+-----------------------------------------------------
Reporter: mabshoff | Owner: mabshoff
Type: defect | Status: new
Priority: critical | Milestone: sage-3.4.1
Component: solaris | Keywords:
----------------------+-----------------------------------------------------
I thought we had fixed this via fast_callable, but it is still there:
{{{
mabsh...@sage:/scratch/mabshoff/sage-3.4.1.rc3$ ./sage
----------------------------------------------------------------------
| Sage Version 3.4.1.rc2, Release Date: 2009-04-10 |
| Type notebook() for the GUI, and license() for information. |
----------------------------------------------------------------------
sage: f=x^(1/3)
sage: f._fast_float_(x)(-1.2)
nan
sage:
}}}
This is exposed via a plotting failure on Solaris where NaNs pop up.
Fixing that in the plotting code is a different ticket William will open
shortly.
Cheers,
Michael
